To all whom it may concern:

Be it known that 1, CHARLES L. LInBY, at

Indianapolis, county of Marion, and State of Indiana, have invented acertain new and useful Tool-Supportfor Lathes; and I do hereby declarethat the following is a full,

clear, and exact description thereof, refer or out of the way of the useand operation of the carriage for other work of the lathe.

The full nature of the invention will be understood from theaccompanying drawlugs and the following description and claims:

In the drawings Figure lis a plan view of a portion of a lathe providedwith a support for a drill, boring bar or the like mount ed inaccordance with my invention, the said support being in working positionand parts being broken away. Fig. 2 is a rear elevation of the centralportion of said lathe, parts being broken away andparts in section. Fig.3 is a vertical transverse section on the line.33 of Fig. 1, showing thetool support in working position. Fig. 4 is the same showing the toolsupport thrown back.

Fig. 5 is a section on the line 55 of Fig. 4;. Fig. (5 is a frontelevation of the tool support and a portion of the rod on which it ismounted.

In the drawings there is shown alathe bed 10 with a head stock 11 andchuck 12 revolubly mounted inthe head stock for holding the work 13which revolves while it is'being treated by a non-revoluble drill ortool 14.

mounted in the turrethead 15. Theouter end of the drill is is supportedby a bushing 16 in the eye 17 of the tool support or guide 18. 1 Saidtool support is carried on the rod 19 by the inte ral. s lit plates 20and 21 which are clamped by the bolts 22.

The rod 19 isrevolubly mounted in bear in brackets 23 secured to the bed10 and he in place by collars 24, and stop projec- Y Patented ltllay Ml,flt'litth tion secured to the rod. 'llhestop pro-- ect1on 25extendsdownwardly and is adapted when the tool holder 1s thrown bass: to

engage the side of the bed 10, as in llig The tool holderis providedwith a boa mg shoulder 2-6 that rests flatly upon the flllfl6- way 2? onthe bed 10 while the tool support is in working position, as shown in.Fig. i

The tool holder is helddown in its work.-

ing position by the clamp bolt- ZEl'that projects through a portion oftool supptu't to the side of the shoulder :36 and the slide way .27;

The lower end of the clamp bolt tit has a horizontally disposederitension 29K that, when said-bolt is turned, the tool sup 011; beingin its working position, said proectio,n 29 will'niove in under theslideway 27, whereby it will cotiperato with the shoulder 26 and theslideway 537 in holding said tool support in its proper workingposition, A stop lug 30 projects downwardly from the under side'of theslideway 2'? in position to limit and stop the rotating: setting movement of the clamping bolt 28. Since the tool sup-port consists of asingle arm :tjulcruined at the rear of the bed and extending up at anlncllnatmn it is out of the Way oi". and

does not interfere with the movement of the carriage on the bed,

to secure by Letters Patent is: i

1. The combination of the bed of a lathe,

a tool holder fulorumcd at one side of the bed of the latheafndconsisting of a single arm with the upper and free end thereof formed tohold a tool and shoulder on said tool holder near its fulcrum adapted tofit upon the upper surface of the same side of the lathe bed as, thepivotal mounting oi'the tool holder and hold the tool holder in aninclined position with the free end overthe lathe bed duringwork, andmeans for stepping the oscillatory movement of the tool holder forholding 1t out of the way when desired; p

2. The comhlnation of the bed of a lathe, a rod mounted at one slde ofthe bed at the What l claim as my invention and desire f ill lathe, atool holder mounted on said rod 30 as to be oscillatory thereon andslidable longitudinally thereof and consisting of a sin is arm with theupper and free end thereof 'ormed to hold thetool and a shoulder on saidtool holder near said rod adapted to fit and slide upon the side of thelathebed emg'res with which said rod is connected and hold ID. *vVitn5Swhereoffl hzwe hereunto affixed the tool holder in anrinclinecl positionwith my slgneture in the presence of the witnesses the free end over thelathe bed during work, herein named.
